React Native - NSInvalidArgumentException

我正在使用react-native-piechart来呈现单个图表。我已将ART.xcodeproj添加到我的图书馆。我还将libART.a添加到我的Build Phases > Link Binary With Libraries。React Native - NSInvalidArgumentException

当我渲染图表时，我的应用程序崩溃。当运行react-native log-ios我得到以下堆栈跟踪

我已经试过

经纱取出包，并从Xcode中移除ART.xcodeproj和libART.a，然后重新安装。
我试过了多个图表库 - 这个问题依然存在。
我创建了一个全新的项目来测试库不会引起问题，他们工作得很好。

你应该该报告为图书馆的发展。 'NSArray'类没有'length'方法，但只有[count]（https://developer.apple.com/reference/foundation/nsarray/1409982-count?language=objc）方法。这是一个bug或者在本地ObjC的'NSArray'类之上实现的一些奇怪的扩展。 –

我不相信这是图书馆@StanislavPankevich的问题，它已经工作了3-4周，并且在单独的React Native项目中工作。我想也许这是我不小心点击Xcode的东西。 – Dan

我唯一指出的是数组而不是字符串被传递给'RNSVGPathParser'的初始值设定项。它试图计算一个字符串的长度，但是碰到了数组，因此崩溃了。我是Objective-C开发人员，不熟悉ReactNative，所以我不能说为什么图书馆走错了路。 –

我在使用react-native-progress时遇到同样的问题。类似的崩溃报告here

要解决我删除引用反应母语-SVG，然后跑：

npm install react-native-svg --save 

react-native link react-native-svg
